a)Three different letter grades can be taken from an exam: A, B and C. A sample dataset created for nine people is given on the side. We want to find out the letter grade a student got from a course by using the working and sleeping hours. For this purpose, separately calculate the w and b values of the linear (h=wx+b) probabilistic SVM classifiers learned with the one-vs-all strategy using the dataset in Figure 1 and Figure 1 draw on it. Figure 1 is showing x axis sleeping time and y axis is for working time.

b)For the classification of the model learned from a section, calculate the accuracy (accuracy) using the test data set in the blow. Show all steps.

Sleep Time Working Time Letter Grade 3 8 B 6 10 B 6 2 A 7 5 A 9 9 8 A 7 4 C 10 8 B 6 A 4 2 2 0 0 2 4 6 8 10
